The aim of the study was to find whether the c.I. test is useful for the exclusion and the demonstration of acquired cognitive deficits. In all, 195 patients with brain damage and 68 neurotic patients were examined with the c.I. test and with a comprehensive number of neuropsychological tests. The hit rate of the c.I.-test for the whole group was 67% and lay lower than the base rate of 74% brain damaged patients respectively only unessentially higher than the base rate of 64% patients with unambiguous acquired cognitive deficits. There were very low hit rates especially in patients with absent (46%) or low-grade cognitive deficit (54%) and with low (55%) or with high premorbid mental abilities (55%). Both the low correlations between the c.I. test and the validity criterion as well as the considerable overlapping of the c.I. test raw score distributions, grouped by grades of cognitive deficits, indicate serious deficiencies in the test. The extremely brief c.I. test possesses an inadequate grade of difficulty and cannot detect low- and medium-grade acquired cognitive deficits, and its orientation to ability-related global syndromes means that partial, multifactorial and general cognitive deficits are neglected. The c.I. test is therefore not useful as a screening method for the diagnosis of acquired cognitive deficits.
该研究的目的是确定c.I.测试对于排除和证明后天性认知缺陷是否有用。总共对195名脑损伤患者和68名神经症患者进行了c.I.测试以及多项神经心理学测试。c.I.测试对整个群体的命中率为67%，低于脑损伤患者74%的基础率，仅略高于明确后天性认知缺陷患者64%的基础率。命中率极低，尤其是在无认知缺陷（46%）或轻度认知缺陷（54%）以及病前心理能力低（55%）或高（55%）的患者中。c.I.测试与效度标准之间的低相关性以及按认知缺陷等级分组的c.I.测试原始分数分布的大量重叠，表明该测试存在严重缺陷。极其简短的c.I.测试难度等级不足，无法检测出轻度和中度后天性认知缺陷，并且其对与能力相关的整体综合征的导向意味着忽略了部分、多因素和一般性认知缺陷。因此，c.I.测试作为诊断后天性认知缺陷的筛查方法并无用处。
